Reconfigure virtual machines configured for backup

Phoenix Editions: File:/tick.png Business File:/cross.png Enterprise File:/tick.png Elite

 

Overview

Druva Phoenix lets you reconfigure your virtual machines if:

  • You want to change backup policy
  • Change administrative group
  • Modify the backup content

After you reconfigure a virtual machine

  • Virtual machine is backed up as per the schedule defined in the backup policy associated with it
  • Backup snapshots are retained as per the retention settings specified in the backup policy
  • The server is listed under the Resources tab of the administrative group you choose for a virtual machine

Note: You cannot change the storage assigned to a virtual machine

Prerequisites

Backup policy and the administrative group should be created before reconfiguring virtual machines for backup. 

To reconfigure virtual machines from the Configured VMs page

  1. Log in to the Phoenix Management Console.
  2. On the menu bar, click the drop-down next to All Organizations and select the Organization.
  3. On the menu bar, click Protect > Hyper-V.
  4. In the left navigation pane, click Configured VMs.
  5. Select the virtual machines on the Configured VMs page that you want to reconfigure. 
    Note:  You can apply filters based on VM name, Host, or Admin Group.
  6. Click more options (see below) to get all the options.

    Field Description
    Enable Backup Click to enable backup of the selected virtual machines.
     
    Disable Backup Click to disable backup of the selected virtual machines
    Change Backup Policy If you select this option, the Change Backup Policy dialog appears that allows you to select a different backup policy. In addition, the dialog displays the backup policy settings, such as backup schedule, retention, and other settings. For more details on the backup policy options, see Manage Backup Policy.
    Select a new backup policy and click Save.
    Change Administrative Group If you select this option, Change Administrative Group dialog appears and allows you to select a different group. Select a different group and click Save.
    Change Backup Method to RCT

    If you select this option, the Phoenix agent can use the Resilient Change Tracking (RCT) feature Windows server provides for Hyper-V virtual machines. For Druva Phoenix to use the Resilient Change Tracking (RCT) feature:

    • The agent version must be 4.7.5 or later, and
    • The Hyper-V host must be installed on a Windows Server 2016 with virtual machine configuration version 6.2 or later. If the virtual machine is hosted on a Hyper-V cluster, then the virtual machine cluster functional level must be level 9 or higher. 

    Note: With the introduction of support for Resilient Change Tracking (RCT), the Phoenix agent uses the native Hyper-V technology to back up the virtual machine files in RAW image format. Before the support of RCT, the Phoenix agent backed up the virtual machine files using the Volume Shadow Copy Service (VSS). With VSS, the Phoenix agent backed up the virtual machine files like flat files. With this change, you may not get deduplication savings for the two different file formats and the storage consumption may increase. However, there is no impact on the backup and restore jobs. You can use older snapshots created using VSS to restore virtual machines on the hosts. For more information, contact Support.

    Field Description
    Administrative Group

    Druva Phoenix lets you create a group for better management of resources. For example, you can create an administrative group for all virtual machines with Linux as the guest operating system. Later, you can directly access all servers using the administrative group page. 

    In this field, you can:

    • Choose an existing administrative group, or
    • You can create a new administrative group

    If you click New Administrative Group, the New Administrative Group window appears. Provide a name and description of the administrative group. For example,

    • In the Name field, enter Linux Virtual Machines
    • In the Description field, enter an administrative group for all virtual machines with Linux Guest OS.
      After you provide a name and description for the administrative group, click Save. After you click Save, the configuration wizard reappears with the group you created as an option for you to select.
